Take it or flush it

I was told that everything you need for great hair is:
iron, B12, zinc, B6, evening Primroe oil, vitamin C the rest I forgot..
Im a bit panicking as I experience quite a "dramatic" hairloss at the moment..Maybe its just the usual change of "fur", or maybe I will be as bald as my Parents are pretty soon?
Its not about vanity, but I wished I was as pretty as next doors neighbours dog smoothie..
PS: Im not a big fan of any medication, even used to flush antibiotics when I was a child- silly me I know- but sometimes they can help, cant they?
